To all whom it may concern: 7

Be it known that I, THOMAS WV. CORKELL, a citizen of the United States,and a resident of the city of Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inCollapsible Barrels; and I do hereby declare that the following isafull, clear, and eXact description of the same, reference being'had tothe accompanying drawings, and to the numerals of reference markedthereon, which forma part of this specification.

This invention relates to an improved type of collapsible barrelconstructed of wood, metal, composition or other material, but, as shownand described, preferably constructed of metal, to afford an exceedinglysubstantial structure.

It is an object, therefore, of this invention to construct a collapsiblemetallic barrel wherein the metallic stave elements are constructed toafford hinge members to receive attaching pintle bolts .therethrough,and with circular metallic arched heads for the top and bottom ends ofthe barrel to fit tightly within and over the edges of the hingedlyconnected stave elements and .to be bolted thereto to afiordsubstantially a unitary structure.

It is also an object of this invention to construct a collapsiblemetallic barrel wherein the staves are constructed of curved strips ofmetal with the margins thereof formed to afford hinge members to receivewherebythe hingedly connected staves may be laid folded around thecircular top and bottom metallic heads provided for the barrel, and withregistering apertures provided between the ends of said stavesand theflanges on said heads to receive attaching connecting boltstherethrough.

It is 11150311 object of this invention to construct a knock-down .orcollapsible barrel whereinv the staves are hingedly connected one toanother and are adapted to interfit with circular heads which afford, abrace and connecting means for the ends of the staves to hold the.sameclisbosed in proper cylindrical form, and with certain of saidstaves adapted to be swung open from the built-up barrel to give accessto the barrel through 7 the side thereof.

It is furthermore an important object of this invention to construct acollapsible barrel embracing flanged. heads adapted to fit properrelation with .one I ably secured thereto to permit ready detach-,

over the staves which are hingedly connected to one another, with-theheads so constructed as to protect and brace the upper ends of thestaves and hold the same spaced in "another and suitment therefrom.

It is finally an'object of this invention to construct an improved typeof knock-down or. collapsible barrel simple in construction and easy. toarrange in assembled form.

The invention (in 'a preferred form) is illustrated in the drawings, andmore fully pointed out and defined in the appended claims. l

Inthe drawings, Figure 1 is a side elevation of a barrel constructedaccording to the principles of my invention. Fig. 2 is a top plan viewthereof. Fig. 3 is a fragmentary interior view of the staves of thebarrel. Fig. 4: is a horizontal section taken through the barrel,showing certain of the hingedly connected staves swung into openposition to .give access to the interior of the barrel.

Fig. 5 is a fragmentary sectional view illustrating the interior of theassembled barrel.- Fig. 6 is a fragmentary horizontal sectional View.similar to Fig. 4, but on a larger scale. Flg. 7 is a fragmentaryplanview of the under surface of a barrel head at a certaln portion of theedge thereof. Fig. 8 is a frag- ,1nentary exterior view of the upper endof the barrel at that portion of the edge of the head shown in Fig. 7.Fig. 9 is a fragmentary detail section takenon line 9-4;) of Fig. 5.Fig. 10 is a detail. section taken on line 10-10 of Fig. 8, showing theremovable locking rod for the opening stave sections of the barrel. Fig.11 is a similar View at the lower end of the barrel, illustrating thelooking nut on said rod. Fig. 12 is a detail section taken online 1212of Fig. 8. Fig. 13 is a detail section taken on line 13-43 of Fig. 1.

As shown in the drawings, the reference numeral 1, indicates one of anumber of similarly constructed metallic barrel staves, each.

of which, on one side, has hinge members 2,

formedv integral therewith and on the other side thereof, similarv hingemembers 8, staggered with respect thereto, so that a number of saidstaves may be arranged with the hinged members thereof registering withone another to receive a hinge pintle bolt or rod t, insertedtherethrough; As clearly shown in Fig. 3, in the'upper and lower ends,al-

though the lower ends of the staves are not shown, are recesses, asindicated by the ref-- erence numeral 5, at the corners thereof, so thattwo adjacent staves afford a recess for the rounded head 6, of thepintle rod 1, shown in Fig. 13. Certain of the staves of J the barreldenoted by the reference numerals tion, consisting of a main archedportion 11,

with an upstanding. flange 12, formed there on, and with the margin 13,of said flange, as clearly shown in Figs. 9 and 13, bent over to afforda recess into which-the upper ends of the stave elements 1, engage. Thatportion of the head, however, which is disposed at the ends of theshorter staves 7 8, 9 and 10, has the small marginal flange struck orflattened inwardly, as denoted by the reference numeral 1 1, and bestshown in Fig. 12, so as to abut against the ends of said aforesaid staveelements and yet not confining the same, so that the same may swingoutwardly, as shown in Fig. 4;.

At the junction of one end of the inwardly struck flange 1 1-, with theoutwardly projecting marginal flange 13, the metal is cut away to afiorda recess to permit withdrawal of a locking hinge bolt or red 15, thelower end of which is provided with a nut 16, as shown in Fig. 11. Thepurpose of so utilizing a removable hinge bolt 15, at this point inplace of a hinge rod 1, is to permit release of the stave element 10,from the complemental stave element 1, so that the respective staveelements 7, 8, 9, and 10, may be swung into open position. The flanges12, on said respective barrel heads are provided with apertures atcertain points to receive inserted therethrough and through registeringapertures provided in certain of the stave elements, small connecting orattaching bolts 17, each provided with a removable nut 18, said boltsand nuts at the top and bottom ends of the barrel acting to maintain thestave elements positively associated with the barrel heads and yetpermitting ready detachment of the heads therefrom to collapse thebarrel by folding the hinge staves one upon another when desired. Aninternal reinforcing ring 19, may be provided for the staves, if sodesired, as shown in Fig. 5.

The operation is as follows: In assembling the barrel, the staveelements 1, are laid fiat in interfitting relation with one another, 2'.0., with the tubular hinge members 2, on one side of each stave elementregistering with the tubular hinge elements 3 of the stave elements laidadjacent thereto, and

the pintle rods 4:, are then inserted therethrough. However, for thosestave elements 7, 8, 9, and 10, which are identical with theconstruction of the stave elements 1, except that the former are adaptedto be swung into open position such as shown in Fig. 1, the heads 11 forthe top and bottom of the barrel are so constructed as to permit theaforesaid stave elements to be opened outwardly. This operation ispermitted due to the fact that the marginal flange let, which lies flatagainst the upright flange 12, of the barrel heads, merely abuts theends of said stave elements 7, 8, 9, and 10, as shown in Fig. 12, thuspermitting the same to be readily swung outwardly therefrom. On theother hand, the remainder of the peripheral marginal flange of each ofthe barrel heads which is denoted by the reference numeral 13, projectsover and beyond the ends of the stave elements 1, interfitting therewithin the manner shown in Fig. 9, thus preventing the stave elements 1,being swung into an open position, and the bolts 17, and nuts 18,engaging through the flange of the barrel heads and the upper ends ofsaid stave elements 1, serve. to retain the barrel heads rigidlyassociated with the staves thereof. One of the junctions between themarginal flanges 13 and 1 1, is cut .away at the upper and lower ends.of the barrel to permit removal of the pintle rod 15, inserted throughthe hinge members 2 and 3, of the adjacent stave elements 1 and 10, atthis point, so that the remaining stave elements 7, 8, 9, together with10, may be swung into open positionby removal of the pintle rod I amaware that various details of construction may be varied withoutdeparting from the principles of my invention. I therefore do notpurpose limiting myself otherwise than necessitated by the prior art.

I claim as my invention:

1. A. collapsible metal barrel, comprising a plurality of stave elementsrecessed at their corners, hinge members formed on each edge thereofwith the hinge elements of one edge staggered with respect to thoseofanother element, headed hinge pintle rods adapted to be inserted throughthe registering hinge elements of a number .of staves laid adjacent oneanother, said recesses receiving the pintle heads, flanged heads adaptedto be inserted into the cylindrical body formed by said stave elements,and

marginal flanges on said heads adapted to engage over and around theends of said stave elements to maintain the same in proper relation.

2. A collapsible metal barrel, comprising a plurality of curved staves,hinge members formed on each edge thereofin staggered relation adaptinga number of said staves to be laid adjacent to oneanother with therespective hinge elements thereof registering, plntle rods adapted to be1nserted through the registerlng hinge members pivotally to connect saidstaves one to another, heads adapted to be inserted into the cylindricalbody formed by said con nected staves, and means "for attaching saidheads to said staves, certain of said staves being free to permit thesame to be swung open to give access to the interior of the barrelthrough the side thereof.

3. A collapsible metallic barrel, comprising curved metallic staves someof which are shorter than the others, hinge members formed integrally oneach side of each of said staves, pintle rods inserted through theregistering hinge members to maintain said staves pivotally connected toone another, and barrel heads around which said staves are adapted to bedisposed and connected and provided with marginal flanges adapted to fitover the ends of the lower staves, said flanges being struck inwardly 0rflattened for a portion of their length so as to abut against the endsof the shorter staves to permit the same to swing outwardly to giveaccess to the interior of the barrel.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing witnesses:
